sclai s. (c1. 137- 68) n This invention apper-tains'to liquid supplying devices, and more particularly to a novel device maintaining the proper level of a liquid in avessel oil in a bearing, engine crank-case, etc. y 3

One of the primary objectsof our invention is to provide an oil supplying device of the reservoir or fountain type, withnovelmeans for quicklyadjusting the reservoir relative to the bearing or crank-case, as the case may be, whereby the desired quantity of oil can be supplied to the point of use and whereby the preferred height of oil in the-bearing or crank-case can be maintained. Another salient object of our invention is to provide means whereby the reservoir can be quickly adjusted to the desiredheight from the exterior thereof without the use "of tools and without the necessity of removing the reservoir from the lubricator. j l I Y i A further important object of our invention is to provide'an oillubricator embodying a removable reservoir of container for the oil mounted upon a supporting reservoir or cu'phaving an adjusting screw axially associated therewithgnovel H means being provided for detachably coupling the reservoir or oil container with the screw, so that uponrotation of the reservoir the screw. will be turnedto hold the reservoir or container in the so desired height. u

A still further objectof our invention'is toprovide an improvedoil lubricator of the above character, which will be durable andeficient in use, one that will be simple and easy to manufacture, andone which can be placed upon the market at a reasonable cost. v r

With these and other objects in view, the in vention consists infthe novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawing; in which: i

- Figure 1 is a vertical'section throughthe improved lubricator;

Figure 2 is a fragmentaryside elevation of the supporting reservoiror cup. i

Figure 3 is a horizontal section through the improved lubricator illustrating the means for detachably coupling the reservoir or oil container with the adjusting screw. i

Referring to the drawing in detail, wherein sim ilar reference characters designate the corresponding parts throughout the several views, the letter A generally indicates our improved lubricator, which comprises a supporting reservoir or islpreferably formed from transparent material,

.top wall ll is provided with an inwardly directed ,threaded'neck l8, for a purpose which will later appear.

Mounted upon .cup 5 whichincludes a cylindrical side wall fiand c a bottom wall 7. which is especially susceptible for automatically The bottom wall 1 at its axial center is provided with a depending nipple'8 and the side wall 6 adjacent to thebottom wall. l is provided with a laterally extending outlet nipple :5 9. A feed pipe to can be associated either with the nipple 9 or the nipple 8 according to the particular type of bearing or the like with which ,the lubricator is associated. In-the present instance, wehave shown the feed pipe Ill connected with the nipple 9' and the nipple 8 isclosed bya removable plug M. This plug H also facilitates the cleaning of the apparatus. The nipple 8v has or supporting reservoir 5 is the adjusting shell 20 I5 and thisadjusting shell I5 includes acylin- .drical side wall I6 and a top' 'wallil'l which is flared inwardly toward its axial center, as shown in.Figure 1. The central portion of the the top wall 11 of the adjusting shell vlt is an oilcontainer orreservoir l9, which such as glass. This container can be in' the nature ,of a bottle and can beconstructed after 7 the conventionalmanners of bottles. This conneck 29' preferably extends into the cup 5- a material distance and the extreme end of the neck carries spaced lugs ortits 22 for detachable engagement with the radially extending arms 23 of the adjusting head 24 rigidly "connected with the innerend of the adjusting or feed From the construction so far, it can be. seen that when the parts are disposed as shown in Figure 1 of the drawing, it ismerely necessary to rotate theshell l5 which-will carry the container l9therewitht Theengagement of'lugs'22 with the arms 23 will rotate the'adjusting or feed screw [4 feeding the screw inward or outward, as the case may be, according to-the direction of rotation of the adjusting shell. Thus, this allows the quick and easy adjustment of the the device without the employance of tools. ,Air channels 25 are formed in the outer face of the cup 5.

.When it is desired to fill the container I9 with the oil, it is merely necessary to lift up on the shell andcontainer and pull the same off of the cupor supporting reservoir 5 and the reservoir or container i9 is turned so as to dispose its neck uppermost. Oil can now be readily poured therein and the shell and container can then be quickly returned to the supporting reservoir or cup 5. By this arrangement, it can be seen that the container can be quickly and easily removed from the cup and placed back thereon andthatthe lugs 22 of the neck of the container will always be in proper position for aging the arms 23 for the adjusting head 24.

In order to prevent the loss of oil from the container l9 when the same is being placed back into' thersupporting reservoir or cup 5, a check valve 26 can be provided. When the container is raised above the adjusting head 2 3 of the feed "screw, the valve 26 seats upon the neck. This valve. 26 can be provided with a stem. 21, the

lower end of which is adapted to engage the upperend of the feed screw when the partslare :properly assembledso that the valve will be held above its seat to permit the flow of oil from the container I9 into the cup. The container with itg'neck 20 can be'built in any desired way to permit the association of the valve 26 therewith and if so desired, the valve can beplaced in the container during the forming of the container.

. If preferred, a set screw 28 can be adjustably associated with the shell I5, so that after the shell and container have been adjusted to the desired height, the shell can be locked with the cup and thus, held against .further rotation.

From the foregoing description,.it can be seen that we have provided a novel and simple form of lubricator in which the reservoir or container can be quickly adjusted to the desired height .to

'suitvarying conditions from the exterior thereof.

'While in the above specification we have described the device ior use particularly as a lubricator, it is to be understood that the principles of. the invention are susceptible .for general use, wherever aliquid supply and level. maintaing device is desired, such as in chicken feeders, air

conditioners and moisteners, etc.
